Has anyone figured out how to create multiple menu containers for hamburger menus? I would like to have hamburger menus on different pages display different vertical menus, but it seems like all hamburger menus share the same menu container so even though it is easy to create different vertical menus there is no way to have them vary across different hamburger menu containers.
When I add a hamburger menu to a page its menu container is shown as a master in the Layers Panel:
It is also listed as "Masters: Menu Container" in the page selector at the top center of the editor:
But it does not appear in the Site Masters Panel, so there doesn't seem to be a way to add a second master menu container by creating a duplicate:
There also doesn't appear to be a way to make the menu container a regular, non-master element, as there is no "detach from master" option when right-clicking on the it in the editor.
I hope I am just missing something obvious. Anyone have any ideas? If not I guess I will just fake it with lightboxes.
